Well It's only a matter of time when people buy one. Regular DVDs are still dirt cheap. We recently features new Blu-Ray DVDs for $8 including older titles like Cujo and Chaos. The cheaper Blu-Ray gets the more adopters will follow. It's all about price.
Me personally just waiting for redbox to have blu-rays, and I will buy the occasional title on Blu-Ray. Probably Avatar.
It's just that simple.
